Arbitrary and capricious

 "A decision is arbitrary if it comes about  seemingly at random or by chance or as a capricious and unreasonable act of  will.  It is capricious if it is the  product of a sudden, impulsive and seemingly unmotivated notion or action."   City of Livingston v. Park Conserv.  Dist., 2013 MT 234, ¶ 10, 371  Mont. 303, 307 P.3d 317 (citation omitted).

A review by a  district court or the Montana Supreme Court "of an action under the 'arbitrary  and capricious' standard does not permit a reversal merely because the record  contains inconsistent evidence or evidence which might support a different  result.  Rather, the decision being  challenged must appear to be random, unreasonable or seemingly unmotivated,  based on the existing record."  Silva  v. City of Columbia Falls, 258 Mont. 329, 335, 852  P.2d 671, 675.
